"Certifié bio." "100 % naturel." "Aux huiles essentielles 100 % naturelles."

Nous retrouvons ces mentions rassurantes partout sur les produits pour enfants. Le message implicite est toujours le même : naturel signifie inoffensif.

Sauf que non.

Les huiles essentielles sont bien des substances chimiques. Même lorsqu’elles sont naturelles, elles sont constituées de mélanges de molécules actives, concentrées, lipophiles et biologiquement puissantes. C’est précisément ce qui rend l’aromathérapie efficace.

Mais l’efficacité est un mot à double tranchant : il existe toujours une contrepartie toxicologique. Sur la peau immature d’un nourrisson, ces substances peuvent provoquer des effets que peu de parents imaginent.

Les filtres inorganiques (minéraux) modernes, comme l’oxyde de zinc (ZnO) et le dioxyde de titane (TiO₂), protègent majoritairement par absorption des UV, et pas uniquement par réflexion ou diffusion.

Les études montrent que la réflexion de la lumière ne représente qu’une petite partie du mécanisme de protection (1). La grande majorité de la protection fonctionne, comme pour les filtres organiques, par absorption des UV (1) .

Une crème solaire « minérale » plus blanche n’est donc pas forcément plus protectrice qu’une crème plus transparente.

Dans les crèmes solaires utilisant uniquement des filtres inorganiques, un effet blanc plus marqué signifie souvent que les particules sont plus grosses et diffusent davantage la lumière visible. À l’inverse, des filtres minéraux plus fins ou mieux dispersés peuvent devenir presque transparents tout en conservant une bonne protection UV.

For several years now, the debate between hydroxyapatite and fluoride has taken center stage in the oral care sector. Many fluoride-free toothpastes promote hydroxyapatite (nHAP), in nano or non-nano form, as a natural and innovative alternative for remineralizing teeth.

At the same time, fluoride is increasingly met with distrust, particularly on social media. However, a large portion of the content creates confusion between two very different topics: water fluoridation and the use of fluoride in toothpastes. These two uses are not comparable.

The fluoride present in toothpastes is applied topically, with controlled doses, and is subject to specific recommendations, especially for children. This therefore has nothing to do with water fluoridation policies.

In modern cosmetic discourse, some terms have become almost automatic: "multivitamin," "ultra-fresh," "nourishing," "fast-absorbing." By reading and hearing them so often, we end up forgetting about a fundamental biological reality: the skin is an organ of protection — not an organ of absorption.

Unlike the stomach or intestines, the skin is not designed to absorb substances into the body. Its primary function, on the contrary, is to regulate exchanges, limit water loss and protect against the environment. It filters, blocks, and defends.

It is also a major sensory organ, thanks to a dense network of nerve receptors involved in touch, pain, pressure and thermoregulation.

Valentine's Day is approaching. A celebration of lovers, red hearts, flowers... and sometimes overly ambitious promises. But one question deserves to be asked: do "love cosmetics" truly exist? Can a cream make us more attached, closer, more tender... or are we talking more about a magic potion like Amortentia in the Harry Potter universe?

When winter arrives, viruses run rampant in daycare centers, mittens mysteriously disappear in pairs, and parents go into hygiene and thermal survival commando mode. But between myth, deep-rooted habits, and fear of doing the wrong thing, we sometimes make mistakes... Here are the 5 most common ones —scientifically analyzed and with a hint of icy humor.

Discover the most incredible teeth in the animal kingdom: elephant, shark, crocodile... and compare them to human teeth!

When we think of teeth, we imagine our own molars and incisors. But in nature, some teeth are true superpowers ! Let's discover the champions of the animal kingdom.

Sodium benzoate (E211) is one of the most widely used preservatives in food and even in some organic cosmetics. It is found in juices, jams, sauces, sodas, and sometimes in shampoos, cleansing foams, and toothpastes.

At LiLiKiWi, we've chosen to go further: completely ban sodium benzoate from all our children's formulas and raise awareness among parents about its risks. This blog is based on the 2022 scientific review on sodium benzoate published in Nutrients ( MDPI, 2022 ) and current European standards.

Mom, I lost my tooth!
It's often around the age of 6 that baby teeth begin to fall out. A moment that combines pride, excitement... and sometimes a little visit from the famous tooth fairy, depending on the culture. But behind this tradition, one question remains: why do we change our teeth when they are so hard and our bodies have spent so much energy making them?

When industry creates the problem… and sells you the solution.
In what we call the Duplomb Law, the same industrial group can intervene both in the creation of an imbalance... and in its correction.
It's a well-established strategy, where health becomes a lever for profitability, not an end in itself.

Did you know that some children's toothpastes contain sugar? So, why do some brands use cariogenic sugar? What is the real impact on children's dental health? Discover the hidden truths and alternatives for a radiant smile! 😁
